A huge advantage with the ERW process

Welding is the most popular method of joining metal. It can be incredibly effective but there are a number of things to think about. For example, you need to choose the right method. This will depend on the type of metal you are working with and what kind of product you are making. If you need tubing, one of the best options is ERW tube. Electric resistance welding provides a number of impressive advantages. However, there is one that really stands out.

No filler

ERW tubeMany types of welding rely on a filler material to help make the joint. These materials melt when they are heated. As a result, they can flow and fill the gap between two parts or metal edges. When they cool, the joint will be ready.

There are lots of different options for weld filler. Common choices include metals like tin, aluminium, and nickel. There are also a number of non-metallic fillers. It is important to choose the right one because it will have slightly different characteristics to the metal parts you are working with. This can cause issues, including corrosion or a different level of hardness.

Another issue with welds is that they can include various discontinuities. This can be things like permanent bubbles, overlaps, and inclusions. If there are too many of these the weld will not be strong enough or will have a huge flaw. As a result it will not meet the necessary standards.

The advantage with ERW welding is it does not use a filler material. Instead the process heats the two edges of the metal and uses pressure to push and fuse them together. As a result, there should be less risk of a difference in properties or excessive discontinuities.
